Boats are sure to be damaged due to regular use and should be repaired immediately at the initial stage, so that the cost of repairing does not go high. Even well-built boats will ultimately develop leaks, simply because boats are not totally firm structures. In fact, they twist and bend quite a bit, and below-par constructed boats flex a lot. Most of the boats in Rockland now have aluminum window frames, which cause leaks. This is usually not the fault of the frame. This is due to the deprived design of the structure to which the frame is attached. The reason behind the leaks is usually because the seal in between the window frame and the fiberglass portion of the boat gets broken. The break in the seal can be so small that one can't even check it normally. This happens because of the capillary effect. The capillary effect draws water into the smallest of crashes and more or less works as a water pump to keep bringing water inside the vessel. Deck hatches generally leak due to deck bends to a certain extent that the caulking seal breaks. Such repair works need to be taken care of without delay.
